In this report I will talk about the three main problems that occur nowadays. First of all there’s the endangered animals: species who are threatened to go extinct. Then we have the toxic pesticides that are used today to fend off illnesses for e.g. plants. Lastly the global warming causes great concern. This report should give a good insight into what we can do to stop these threats.
Firstly, endangered animals are a great concern to many geologists. When species go extinct, the other species will roam freely. When for instance a plant-eating kind of rabbit has gone extinct, the plant it used to ate can now grow wherever it wants: there’s no holding back. The insects that live from or on the plant can also multiply easier, and this way a whole ecology can change. Therefore we shouldn’t build houses wherever we want: it might kill the one species that maintains another species. Also, we have to be careful what animals to hunt: killing the prey will also slow the growth of the rabbits down.
Secondly, the poison used to fend off illnesses or insects which eat crops is very dangerous for the environment. Accumulation is the main factor: the pesticides kill the insects, and the birds eat the insects. When the predatory bird eats the other birds, it gets so much toxin that it will die too. This way people can wipe out many types of birds and insects, which is devastating for the rest of the environment. That’s why farmers should either use biological products or prevent the birds from eating the poisoned insects, in one way or another.
Lastly, there’s the global warming. This may cause all of us problems, throughout the world. When ice melts, the water level will rise significantly. Cities under the water level will flood, and whole countries can be washed away. Of course everything happens very slowly, but in a few 1000 years people will definitely be in trouble. Global warming also making climats change, and animals as well as plants will have a really hard time adjusting this fast to the changes. Therefore we should try to cut down on the use of electricity, and consider travelling in other ways: instead of going by car, we should go by public transport or walk to nearby places. Even buying vegetables and fruit that come from our own country will help cut down the emission of greenhouse gasses.
All this means changing the way we live now, and it might be tough, but we should think about what damage we couse the environment and other animals. We have to be careful when building new buildings, use biological means to fend off unwanted animals or diseases, and rethink the way we transport ourselves, as well as our food.
