Task1
I think environmental scientist is the most rewarding job. Nowadays, as the industry developing rapidly, we are facing more and more serious environmental problems, especially global warming and water pollution. And if things kept developing like this, billions of people would be surrounded by dangerous factors. However, an environmental scientist can help people solve these life-concerning problems using his own professional knowledge, which could gain himself great sense of self achievement. According to Maslow’s hierarchy of happiness, this sense could help people acquire the utmost happiness. Besides, he could also gain public recognition through his action, which to my eyes, is more valuable comparing to other rewards, money for example.
