why do we have to preserve the environment

3. The problems with chemical
Other farming practices can impact the climate. Pesticides and fertilizers are widely used in farming, and are often made from fossil fuels. Manufacturing and transporting these chemicals uses some amounts of energy and produces. Studies have shown that chemical farming uses more energy than organic farms, which do not use these chemicals. In addition, the use of nitrogen fertilizers in soils produces nitrous oxide, a greenhouse gas that is approximately 300 times more powerful than carbon dioxide at trapping heat in the atmosphere. Organic farms, on the other hand which rely on natural manure and compost for fertilizer store muck more carbon in the soil, keeping it out of the atmosphere.

Where your food comes from is also important. Currently, the average meal travels 1200 km from the farm to plate. Food that is grown closer to home will have fewer transportation emissions and also be fresher and support local farmers. And as the distance food travels decreases, so does the need for processing and refrigeration to reduce spoiling the food. Choosing to buy food that is organically grown can therefore be a better choice for the climate. But if possible, buy food that that is organic and local. Ways to help stop pollution! 1. Reduce, Reuse, Recycle Do your part to reduce waste by choosing reusable products instead of disposables. Buying products with minimal packaging (including the economy size when that makes sense for you) will help to reduce waste.

And whenever you can, recycle, newspaper, glass and aluminum cans. If there isn't a at your workplace, school, or in your community, ask about starting one. By recycling half of your household waste, you can save 2,400 pounds of carbon dioxide annually. 2. Walk and save money! Walk to school instead of driving in a car! this will save money,fuel,and pumps less carbon dioxide in the air. One of the most important reasons to protect the environment is because it helps protect different ecosystems. Over the years, humans have discovered that many ecosystems are more complex than was originally thought and are deeply connected to other ecosystems.

Human changes to one ecosystem, whether through environmental pollution or deliberate manipulation, can actually put multiple species in danger of extinction, necessitating the need to protect the environment. Protecting the environment also protects humanity. A great deal of pollution, especially ocean pollution, ends up affecting creatures that humans later consume, meaning that humans are ingesting toxins. The final reason to protect the environment is that humanity has a moral obligation to the world and its creatures. Humans are responsible for taking care of the world, and protecting the environment is one way to be responsible stewards of the world entrusted to their care.
