First Assignment

Climate change involves many aspects of our lives; however the main cause of global warming is the air pollution due to ozone emissions. Humans are the main producers of these prejudicial gases. There are many actions that have been addressed to solve these problems; however, pollution is still really high. In my field, business, the global warming had played and will play in the future and important role. One of the main aspects that will benefit the economy, and at the same time the global warming are renewal energies. Renewal energies are relatively new, but they are been developed really fast. There are already many industries that focus on this new ways of getting energy. In my opinion, they will be very helpful for the environment, and hopefully we will be able to see positive results.
