Many environmental groups are warning that oceans of the world are in great danger. In the past 50 years, the number of water with zero oxygen(氧气) in the open ocean has increased more than four times. In the near coast water bodies, including the river mouth and seas, low-oxygen areas have increased more than 10 times since 1950.Scientists discover that oxygen continues dropping ever outside these zones as the Earth warms. To stop the drop, the world needs to control in both climate change and nutrient(养分) pollution.
Oxygen is a must to life in the oceans. The drop in ocean oxygen is among the most serious effects of human activities on the Earth's environment.
This is the first time for the scientists to take such a deep look at the causes, results and solutions to low oxygen worldwide, in both the open ocean and the near coast waters. About half of the oxygen on Earth comes from the ocean. However, mixed effects of nutrient loading and climate change are greatly increasing the number and size of "dead zones" in the open ocean and the near coast waters, where oxygen is too low to support most sea life.
In the areas traditionally called "dead zones", like those in Chesapeake Bay and the Gulf of Mexico, oxygen drops to levels so low that many animals have trouble in breathing and die. As fishes run away from these zones, their living areas become smaller and smaller. But the problem goes far beyond "dead zones". Even smaller oxygen drops can hold up the growth in animals and lead to disease or even death. Low oxygen also can cause the release of dangerous chemicals. Although a few animals can grow well in dead zones, overall biodiversity(多样性)falls.
I take time management very seriously. I read on the subject and take online courses to master the latest methods. {#blank#}1{#/blank#} When all my tasks are complete, I feel like a champion.
This year, there are more things to do. So I went in search of something newer, better. {#blank#}2{#/blank#} Timeboxing is regraded as the most useful skill. It helps you translate a to-do list into certain time on your calendar. In short, it gives you a plan for what to do and when.

{#blank#}3{#/blank#} We all have to choose every day. With a timeboxed calendar, you don't need to make choices between tasks. This way, it creates more brain space for important work.
It enables us to wisely prioritize(优先处理). {#blank#}4{#/blank#} It is natural to pick tasks which need to be dealt with as soon as possible. A timeboxed calendar can help you decide those tasks wisely.
It avoids the "planning fallacy(谬误)." We may not realize how long the tasks will actually take and think we can get things done quickly. In fact, it usually takes three times longer to finish a task than we think it will. {#blank#}5{#/blank#}
Using a timeboxed calendar is a game changer for me. You can also turn your to-do tasks into achievements with it.
A. Finally, I found timeboxing. B. It saves the time and energy for choice. C. Then we can save lots of time to do other things. D. On a long to-do list, which task should we do first? E. Good time management gives me a sense of real satisfaction. F. Timeboxing helps you get better at predicting how long a task will take. |
