3 câu cuối của bn ý nghĩa hơi lủng củng

The-> the(không cần viết hoa).

Giữa "the internet" và " which" không cần dấu ",".

Giữa "use" và " is" không cần dấu ",".

Chech-> check(sai chính tả).

Work hard-> working hard(Vì ở đây cần danh từ chứ không phải động từ).

Giữa "hard" và " we" cần thêm dấu "," để ngăn cách trạng ngữ và thành phần chính của câu.

Chữ "or" thứ nhất nên thay thành dấu "," vì không nên lặp từ.

Friends and relatives-> relatives (vì relative(n): người thân, bao gồm cả bạn bè).

Trong văn nói, từ xưng hô không nên là "I" mà "we" vì chỉ chung tất cả mọi người.

For policymakers, answering these questions in near-real time is difficult due to the delay in gathering economic, social, and financial information through conventional means. Large technology companies have made available human mobility data that makes it possible to monitor the impact of the COVID-19 interventions in near real-time worldwide. In this blog, we will illustrate the use of this data to measure impact here in Vietnam, which was recently hit by a second wave of COVID-19 infections.

On July 24, after 99 days of zero community-transmitted COVID-19 infections, a 57 year-old man tested positive in Danang, a major city in central Vietnam with close to 1.5 million inhabitants. Within three weeks, almost 600 people were infected, over 25 deaths recorded. Most of these cases remained concentrated in and around Danang. Authorities were quick to respond to the outbreak: the city was swiftly shut down with an estimated 80,000 tourists evacuated, most hotels and businesses closed, and nearly all domestic and international flights cancelled. Importantly, this approach differed from the policy in April, when a state of emergency was adopted nationwide for three weeks. This time in Danang, Vietnamese authorities opted to implement a strict but localized lockdown instead.

Humans impact the environment in several ways. Common effects include decreased water quality, increased pollution and greenhouse gas emissions, depletion of natural resources and contribution to global climate change. Some of these are the direct result of human activities, whereas others are secondary effects that are part of a series of actions and reactions.

One of the biggest impacts humans have on aquatic systems is excess nutrient inputs. Nutrients, like nitrogen and phosphorus, are essential to the health and survival of aquatic plants and animals. However, humans introduce large quantities of nutrients, primarily through overuse of fertilizers. Too many nutrients can rapidly reduce water quality by causing overgrowth of certain bacteria and algae that use the oxygen necessary for other species to survive. Even more problematic is that these nutrients can be transported downstream to other streams, rivers and bays. Therefore, nutrients can reduce water quality in places far removed from where they were first introduced.

The majority of air pollution is the result of human activities. For example, increased fossil fuel combustion from motor vehicles, industrial factories and power plants all pump large quantities of air pollutants, such as carbon monoxide, ozone and nitrous oxides, into the atmosphere. Other air pollutants, such as lead-based compounds, can lead to serious health effects like cancer, or other types of reproductive effects and birth defects.

According to the U.S. Environmental Protection Agency, human activities are largely responsible for an increase in temperature around the globe, primarily due to carbon dioxide and other greenhouse gas emissions. This increase in temperature is leading to changes in where crops can grow and where certain fish or animals can be found, all vital for feeding an increasing human population. The rise in global temperatures is also causing glaciers to melt, releasing water that causes sea levels to rise and threaten coastal communities and economies that rely on coastal resources.

There are several simple things that people can do on a daily basis to minimize their impact on the environment. For example, taking public transportation, biking or walking instead of driving will reduce carbon dioxide emissions. Reducing the amount of fertilizer applied to lawns, gardens and vegetables will lessen the likelihood of water pollution nearby, which is also beneficial for drinking water and human health. Using less energy in the home can lessen the amount of pollution put into the air by coal burning power plants. Any activity which reduces water and energy consumption can lead to positive impacts on our environment.
