Dear friend,

Nowadays, people polluate so much nature that it is already "suffocating", trying to still survive. Creating new things, mankind forgets about trees, seas, oceans, plants, animals and so on. Unfortunately, myself, I am only one person, so I cannot change the whole world. On the other hand, I can change my befaviour towards nature so that I won't worsen it anymore.
For example, many people throw the garbage everywhere instead of doing it into the right places - something I do regularly (I mean, I only throw the garbage into the right places). I am not into killing animals, so if I go to the forest, I only do it in order to breath in fresh air. Also, Saturdays have become the days when my neighbours and I are cleaning our yard to make it more beautiful.
I could do a bigger list of what I am trying to do in order to fight against polluation, but now, I would like to see yours!

Have a nice day!
Sincerely yours,
