Environment

The environment refers to the sum total of all living and non-living elements surrounding an organism, influencing its growth, development, and survival. It encompasses various components, including the atmosphere, hydrosphere, lithosphere, and biosphere, and their interactions. Understanding the environment is crucial for addressing environmental issues, promoting sustainability, and ensuring the well-being of ecosystems and human societies. Here's a detailed note on the environment:

Components of the Environment:

1.     Atmosphere:

The layer of gases surrounding the Earth, consisting mainly of nitrogen, oxygen, carbon dioxide, and other trace gases. It plays a vital role in supporting life and regulating climate.

2.     Hydrosphere:

Encompasses all water bodies on Earth, including oceans, rivers, lakes, groundwater, and ice. Water is essential for life and various natural processes.

Efforts to address environmental challenges require global collaboration, responsible resource management, and a commitment to sustainable practices.

Global warming

Global warming and other air pollutants accumulate in the atmosphere and emit infrared radiation that then heats the oceans to a higher temperature, creating a blanket of greenhouse gas emissions. This process is called "greenhouse gas" gases or GHGs (greenhouse gas). The natural processes by which CO₂ and other greenhouses are removed from the atmosphere by rain and snow are called the "physical process". However, the increasing amount of air pollution, the rapid growth of population and commercial use of coal-based energy generation for power, and even fossil fuel development have all been recognized as causes of global warming. There are some sources of greenhouse gas emissions which include:

Ø    Burning coal,

Ø    Using oil and other fuels like natural gas,

Ø    Manufacturing and transporting goods and services,

Ø    Transportation,

Ø    The release of smoke,

Ø    Deforestation,

Ø    Agriculture.

Burning Coal and Oil

As mentioned earlier, to keep a steady supply of energy, humans need to burn crude oil, which can pollute the air very badly. People need to burn it without thinking about the environment or how their lives would be affected if they did not. It needs to be burned with lots of charcoal which will generate toxic oxides like carbon monoxide and sulphur dioxide into the air. These oxides are released into this air when burning crude oil which makes these pollutants harmful. If these fumes were pumped out of these industries, we might be able to clean up our environments without harming ourselves so much. We also have to create more room for plants growing in those areas, but it becomes too difficult so we have to destroy them by cutting trees down.

Deforestation/Tree Cutting

When there is deforestation of trees, the soil gets contaminated and because of this, the land also gets polluted. Trees are also used to make paper products which are important things when it comes to papermaking but instead of using natural raw materials from the forest, people just cut down trees to make paper products. They cut down trees everywhere, which is not good for both worlds and animals. Also, due to industrial farming of food crops, we are eating less healthy food and losing the earth to chemicals. So for example, the livestock industry is highly damaging to the planet because when farmers use fertilizers and pesticides on their farms they are releasing nitrous oxide and particulates into the air and soil. This has been known since the 80s, but now everyone is aware of it and many people want to do something about it. And this is why many countries are trying to stop the production of soybeans and also how to get rid of animal diseases like foot rot which is very much prevalent in most parts of Asia.

Agriculture

Animals are one of the biggest contributors to air pollution. For example, cows are responsible for 7% of global methane emissions and if cows had to be kept separate, they would only grow 1kg per day. They are constantly breathing in all these fumes which causes respiratory irritations and the lungs will get infected due to breathing it all in. That’s called an “aerosol”, these gases are produced through photosynthesis and they can be damaging because they are high in sugar which means they affect our health. Cattle are an enormous cause of air pollution as well. Because cattle are raised indoors, animals eat a lot and therefore produce methane, a gas that is responsible for almost 20% of atmospheric greenhouse gasses. The milk from cows is contaminated by lactose which can make us weak. And they can also give birth to human babies which can cause some problems as soon as they develop. Also, cattle can easily get cancer-causing bacteria such as Salmonella. Other than these animals, we also have big farm animals like sheep and goats who are also one of the biggest contributors to air pollution due to their massive size. But they cannot be sold indoors and they are kept outdoors which makes them an easy target for animals like mosquitoes and other animals who can also contaminate the air in large amounts. Lastly, livestock produces waste products that can further harm the area and become a hazard to humans. Crops also release nitrogen into the air and it is considered one of the biggest contributing factors to climate change. What Kind of Food Do I Eat? Food is another source of air pollution due to the huge demand. In times when everything is limited, we have to find a way to make food with limited resources and in turn, it produces a tremendous amount of methane and other gases which affect our health. Thus we have to limit what kind of foods we have access to, but to a lesser extent. How Am I Going To Stop Pollution Or Control It? There are many ways to help.

First, when going shopping go to make sure you look at the ingredients in every product and not only what it sells but what also impacts your wellness and daily life. Also try to think what kind of impact it can have on the environment, such as packaging, transportation, etc. You can also try switching to low-impact activities. For instance, cycling or walking around the room will make you less tired and stress-free at the end of the day. Instead of buying fast food, have a salad instead. Even though McDonald’s, Subway, Burger King, Starbucks, Starbucks coffee shops and plenty more coffee shops do this, it is not sustainable. Second, start gardening with lots of fresh vegetables and fruits to reduce the number of fresh organic fruits and vegetables. Additionally, there are tons of apps available online which will help you monitor how much fertilizer you use, monitor the water, etc etc. Try composting, turning off lights, and avoiding excess water usage. Third, get yourself a reusable bag for groceries. Not only will you recycle every empty container but they can also save money on buying new ones. Then you can get out your grocery bags and fill them with essential items to ensure no contamination, and to prevent any spills along the way. Fourth, if you want to make eco-friendly alternatives for clothing, try using recycled jeans and t-shirts. Fifth, use biodegradable polyester fabric instead of cotton. Also, switch to organic and ethical materials. Another thing you can do is make your soap. It is a great alternative to plastic bottles.

Environmental pollution

Definition

The term "environmental pollution" means any activity that negatively affects the environment, including:

Ø    Changes in soil and water conditions,

Ø    Formation or occurrence of toxic substances,

Ø    Release of pollutants, chemicals, or particulates into the environment,

Ø    Deterioration of the quality of air, water or land surrounding areas or other critical ecosystems,

Ø    Destruction or damage of physical infrastructure such as buildings, roads and bridges,

Ø    Spread of invasive species, disease-causing organisms, etc.

Hazards from activities of human beings include global warming, ozone layer depletion, acidification of lakes, reduction of biodiversity, loss of agricultural lands, extinction of natural resources, loss of habitat, climate change, and increased noise, vibration, and light pollution, oil spills, noise, and odorous emissions.

Causes and impacts of environmental pollution

Human beings have an extensive impact on the natural world. From industrial sources such as burning fossil fuels, mining metals, cutting forests, manufacturing synthetic materials (such as paper products), and discharging effluents (such as sewage), human civilization has resulted in a dramatic increase in the level of pollutants in our surroundings. There is no natural function for some of these pollutants, so they have become the main source of global warming. The most well-known environmental pollutants are sulfur oxides (SOx), nitrous oxide (NO), and ozone atoms (O3). Each pollutant has its own characteristics that make them dangerous and their harmful effects are many. Besides, each pollutant can harm many animals. In addition, each pollutant can have different types of effects on people and the whole society. A number of ways to deal with this problem of environmental pollution are to reduce the amount of these contaminants and make sure that there is sufficient clean water, air, and land. However, it is difficult to completely solve this problem because each pollutant is a kind of chemical and there are millions of them. So it is difficult to develop a single solution and many actions can be needed in order to reduce the number of pollutants on our planet. Some effective measures include using renewable energy or other environmentally friendly industries such as the production of solar panels or using more efficient transportation systems. Another way to minimize harmful pollutants is to minimize their use by producing organic plastics. It is also possible to decrease the use of fertilizers. However, one must ensure that these procedures do not damage soil and other natural environments. This is possible when we use less harmful and environmentally friendly methods and methods. We can also limit the discharge of wastewater from factories and use biodegradable and recyclable materials, as opposed to those that use non-biodegradable or non-recyclable materials. Thus, recycling is an important issue for a cleaner environment.

Conclusion

Many natural and manmade things can harm the environment. If we did nothing, our world would already look very different. All in all, the best way to protect and conserve our nature is to reduce pollution not only within ourselves but also throughout the entire planet. Therefore, we should try to avoid polluting and save our oceans, air, and ground, and so on from being polluted.

 

Climate Change

Introduction

Climate change has become a global epidemic. It has been observed that the effects of global warming are already becoming visible around the world. The majority of these effects are being felt more and more and have resulted in substantial environmental consequences. With every passing day, it seems like the earth’s atmosphere will be severely affected by human activity. The increase in temperatures and the rising sea levels have put unbearable pain and suffering on many people’s faces. It is no longer possible to ignore the fact that there is an increasing risk of another catastrophic event. That is why the citizens of different countries have come up with various plans to limit their carbon emissions and reduce the rate at which they contribute to climate change. One such place that deserves the highest praise is the United Nations (UN)’s Green New Deal. This program is based on several principles of action, which include the following areas: energy poverty, biodiversity conservation, protection of natural resources, and promotion of green economic transformation. To add to the list of key goals of this initiative, Pakistan is also part of the UN community and its mission is to promote sustainable development and protect climate-sensitive sectors of society through adaptation and resilience efforts.

Climate Change Impact

The impact of climate change is felt around the world. Climate change has a direct impact on the living conditions and culture of most regions of the world. In addition to this, climate change can affect the health of almost everyone on the planet. According to one study conducted by scientists from Oxford University, in 2015 when the temperature increased by 3.5 degrees Celsius over the average between 1950 and 2000, more than half or 57 percent of all deaths were linked to extreme weather. Another estimate shows that during the period in question, 486,000 people died due to heat-related issues, which is 6 times the number of deaths linked to air pollution. As for the cultural and physical impacts, according to some studies, about 30% of the land in Pakistan is under threat from climatic change. This might not seem like a lot to some nations but considering the importance of Pakistan's agriculture, the country could be losing more valuable agricultural land and its products. Furthermore, the region is losing about 11 million hectares of forest area each year and is expected to lose even more by 2050. Pakistan is among the top few countries having lost large tracts of land since 1991 and this has led to serious implications for food production and agriculture. Thus, what is left of this huge, prime agricultural land is nothing but dust and dirt. However, experts and researchers see no reason for panic. They are confident that the country can recover from these detrimental damages if the right measures are taken to prevent climate change.

Effects

The effect of climate change can vary depending on how much we can control it. Some experts believe that for the rest of humanity, any temperature rise will be unfavorable for all societies. Even if we do not manage to eliminate the effects of climate change, the whole of humankind will not face such severe consequences. If we manage to do this, the planet will still be habitable for future generations and any negative effects will be mitigated to a higher degree but will still be there. Scientists have estimated that the damage to the environment resulting from CO2 emissions can reach $100 trillion by 2030.

Conclusion

In conclusion, we need to realize the gravity of the situation and take immediate, decisive steps that would lead us toward a safer and healthier life. We need to stop the further deterioration of our environment so that we can live in a more peaceful world. This will be the sole responsibility of everyone and the whole of humankind who is responsible for this mess. So, stay calm and don’t get stressed out. There are no easy solutions; however, we can try to make things better. At the end of the day, we have the authority to save the planet and its inhabitants, but only if we decide to act now.
