\(\text{So, 00 = -1, 000 = -2 and 0000 = -3. and it follows that 000 + 0000 = -2 + (-3) = -5}\)

The number of old people is increasing rapidly in many countries. This has both advantages and disagvantages for each country.

Due to their extensive experience in life, they can guide the youth generation. As a illustration, when teenagers have to face a complicated problem, they often seek advice from someone older than them. Moreover, teachers, researchers or politicians usually require experience and elderly people can easily contribute to that country's career.

On the contrary, in some countries where the economic develops slowly, old people are often a burden. People in those countries have to suffer from vast poverty and elderly people often don't work. Moreover, young genaration cannot earn enough money to pay taxes and even survive.

There are several farming activities in Vietnam that can have a negative impact on the global temperature, including:

1. Rice cultivation: Rice cultivation is a major source of greenhouse gas emissions, primarily due to the production of methane during the decomposition of organic matter in flooded rice paddies.

2. Livestock production: Livestock production, particularly from cattle and buffalo, is a significant contributor to greenhouse gas emissions through the production of methane from enteric fermentation and manure management.

3. Pesticide use: Pesticide use in agriculture can lead to the emission of greenhouse gases, particularly nitrous oxide, as well as contribute to soil degradation.

4. Deforestation: Deforestation for agriculture, particularly for expanding rice paddies or livestock grazing areas, can contribute to the release of carbon dioxide into the atmosphere.

To address these negative impacts, some alternatives that can be considered include:

1. Sustainable rice cultivation: Alternative rice cultivation methods, such as aerobic rice cultivation or the use of alternate wetting and drying methods, can significantly reduce methane emissions from rice paddies.

2. Improved livestock management: Improved livestock management practices, such as better feeding and manure management, can reduce the emissions of methane and other greenhouse gases.

3. Organic farming: Organic farming practices, including the use of natural pest control methods and composting, can reduce the use of pesticides and fertilizers, as well as promote soil health.

4. Forest conservation and reforestation: Conservation and reforestation efforts can help to reduce the release of carbon dioxide from deforestation and promote carbon sequestration in new forest areas.

Overall, a shift towards sustainable agriculture practices and land use management can help to mitigate the negative impacts of farming activities on the global temperature.
