Summer is the warmest time of year. Long sunny days alternate with short warm nights. The weather outside is often clear, with endless blue sky scattered overhead. Trees stand lush in bright green robes. Below them, grass grows thickly, strewn with colorful lights of summer flowers - poppies, bells, clovers, tansy, chamomiles, marigolds... And butterflies flutter over them and all sorts of flies buzz. Summer decorates gardens and gardens. Juicy cherries sing, followed by apricots and peaches. The big red strawberries lean low to the ground. Gradually "sunbathing" in the rays of the summer sun is still recently green tomatoes. Cucumbers are tied here and there along the arches. The blackish spiny twigs of blackberries are strewn with sweet, dark blue, almost black berries. And so everywhere - a riot of colors, a festival of fertility, a pleasant feeling of warmth and comfort. In the summer, a wonderful ringing voice - the birds singing high in the sky or the birds hidden in the branches of the tree - maestro-nightingale, morning lark, cheerful talking sparrow. And towards the evening the music of summer changes - a chorus of crickets enters, which stops silent until the morning.
Our planet will become cleaner if people protect the invironment. People should participate in clearing up cities. I dream of pavements and paths for people becoming wider. Parks will be built instead of factories, and a lot of new forests will be planted. The air on our planet will become cleaner and fresher.
There will be many safari parks on the Earth. People will treat animals with care. There will be agreement and balance between people and animals. I hope that poachers won`t kill endangeredand dissppearing animals. Many species are included into the Red Book of the planet now. I feel sorry for the animals which are extinct in the nature. Animals are our "lesser brothers". People should defend animals because on the Earth there are very few rare species of animals left. If we want to have the Future, we should take care of our Present! And we should always keep it in our minds: the wildlife treats us the way we treat it.
This is what I dream of, and I want to help the planet I live on.
