Dear Michael,  

Hi! Thank you for your letter. I should say that you are spot on! To my mind, air pollution is the most dangerous ecological problem. Pollutants in the air aren't visible but negatively affect people, nature and animals. They are very harmful for everybody`s life and health. Air pollution is linked to serious diseases, such as asthma, cancer, heart problems. Personally, I participate in voluntary projects connecting with litter collection. We remove rubbish on the river banks in autumn. I think people can limit this problem by reducing rubbish. I like the idea of separate collection of waste. People must be aware of ecological problems. There are many ads on social media, which attract people's attention to ecological problems.  

 

Best wishes,

Alex

This is probably one of the greenest buildings in the world. The 54-storey building was built to use natural daylight for as long as possible. It also has solar panels, rainwater collectors, and materials for the construction of the building itself are made from recycled waste from New York.

Это, вероятно, одно из самых "зеленых" зданий в мире. 54-этажное здание было построено таким образом, чтобы использовать естественный дневной свет как можно дольше. Так же здесь установлены панели солнечных батарей, сборники дождевой воды, а материалы для конструкции самого здания сделаны из переработанных отходов Нью-Йорка
