Read the text carefully then do the activities

On April 22, 1990, more than 200 million people from 140 nations joined in celebration of Eath day in one of the largest demonstration in history . The participants spent the day panting trees, protesting industrial pollution. Learning how to recycle waste, and calling out to world leaders to pass new laws to protect the plant’s environment.
Many years later, there is unfortunately still much to heal. The list of environment problems plaguing the planet is long and growing. Many, such as global warming and depletion of the ozone layer, were unknown just a decade ago. However, there is reason for optimism. Solutions are being developed and progress is being made.
The progress can be measured in the fight to control air pollution. Industrial plants and motor vehicles pump out several hundred million tons of sulfur dioxide, carbon monoxide and soot into the air every year as waste products. But technological advances that were not around two decades ago have reduced the flow of these contaminants into the atmosphere. Scrubbers and other devices filter the gases emitted by factories trapping much of the waste produced catalytic converters make car engines work more efficiently and reduce the amount of smog- producing compounds released into the air.
