10% Can money buy happiness? People have always wondered 1. money really makes them happy. Researchers used to believe that it is up to a certain point happiness increases with income: beyond an annual income of $75,000, people are no happier with higher salaries. 3., recent studies have indicated that happiness still increases when salaries are higher than $75,000. The main reason that money seems to bring happiness is 4. more money can bring greater financial security. Daily activities such as grocery shopping are easier when most of the anxiety regarding what 5. is removed. In this way, money could be viewed as a solution problems. 6. one's on individual Most studies related to this question are based on averages rather than experiences. 7., there are many exceptions to the rule that happiness increases with 8. making $25,000 per year. By contrast, one's income. Some people are satisfied others feel that millions of dollars are required 9. their desired lifestyles.

It's widely known that bees are important for our ecosystem and that they are facing increasing threats from modern agricultural practices involving pesticides. What many of us don't know, 16. (is that some industries should shoulder a bigger share of blame than they're given.) The almond industry, for instance, has quite an adverse impact on bee colonies. One potential harm to bee colonies is the stress caused by transporting them over long distances to almond orchards for the task of pollination. This transportation can be stressful for the bees, hence 17. them more vulnerable to diseases and pests. Moreover, since they're 18. having limited food sources aside from almond flowers further weakens bee colonies. Still another problem is the of honeybees to pesticides and other chemicals used in almond production. 19. 20. and One sustainable solution is to make habitats and species within almond orchards more stable. By creating various ecosystems and introducing other insects among almond trees, at least we can ensure enough food supply for bees and even lower the use of pesticides for almond trees in the long run.
