One side is water and soil, and the other side is people. One side is soil and water, and the other side is the law of nature. Invasion of alien species will cause flooding and great harm. Excuse me, is there a large number of immigrants outside? Only worthless alien species will flood. Think about what you eat and use now, and how much of it is native to the local area. Many people are good, aim high and preach blindly. Look at the number of immigrants to know whether a country is good or bad! It's definitely not good to have more immigrants, mainly because China people have been working too hard, which leads to too much job competition in many countries, so many countries are very strict with China immigrants.
