Your post really sheds light on a lot of things with the photographs. Nowadays, people do not give much importance to trees and plants. He cuts trees for his own needs. You have presented it well here. If there are plants, there is clean air. And if there is clean air, then there is life. @joanstewart
Trouble is watching people buy a home, hardly in the house for a month when removing growth that has sometimes taken years to establish. Legally one can do nothing but advise against it.
Make people more aware about how reliant we are on nature around us it the best we can do. Buildings where people live more congested these plants are safe for children to grow up with inside the home, bringing a little nature in for child to learn their importance as well.
I just saw a video where a guy was spreading awareness about trees. In which he had a temperature measuring machine. You wouldn't believe that there was a temperature difference of about 4 to 5C between the trees and the open space. This is really something to mark. Temperatures are rising in India. At present, the temperature of some areas here comfortably reaches up to 40C. This matter is really noteworthy. He also used to say that it takes 4 to 5 years for a tree to grow, so when we grow so many trees, the temperature here will come down. That too after 5 years.. @joanstewart
Many regions here are stripping out trees to grow indigenous, water wise plants wherever you able. Currently heading into Winter at 30 deg C today which is warm for this time of year.
Couple of years ago I went through series Nature is Speaking the more we learn to respect nature, plant suitable, we will make a massive difference to what we see around us today.
Your point is true and understandable. If everyone thinks like this then there is no need to think to save nature because everyone will give their time for nature. That's all there is to do.
