How I Protect Nature

Every day more and more technical devices are produced to make it more comfortable and easier for people to live and work. However, in pursuit of convenience, we forget that we need to take care of environment. We thoughtlessly consume natural resources, rarely thinking about what kind of world our future generations will live in. Meanwhile, each of us is able to contribute to protection of nature.

I have been thinking about the ways I can help to save nature. First of all, my parents and I try to walk more or ride our bicycles. Each time we keep away from using our car, we reduce air pollution and consume less oil. We also remember to switch off lights and avoid using disposable cups and plates, as well as plastic shopping bags. I always go shopping with a reusable canvas bag. Besides, we buy recyclable paper products to protect forests. I collect used papers, old newspapers, magazines, bottles and any other things that can be recycled. Another great way to protect our nature is to take part in river cleanup events in your city and collect litter that could destroy the natural homesites of birds and fish.

These may seem small and simple things, but they help to protect nature.

My best friend is a very nice boy. His name is Mark. He is very funny, he knows many jokes and like to scare other people. Every time he makes people laugh. But usually he can be very curious, so he can do many bad things. We've met in the plane. We flew in Florida together. I liked him so much there, so we became best friends. We spend time together usually in cinema, or in the park, where we eat ice cream and laugh together. Sometimes we meet at his home, where we play computer games together or play football. So yes, I have much fun with him!
