Disagree with the statement that "the Earth can support seven billion people now and will be able to support any number of humans in the future."

The Earth's resources are finite and limited, and human activities such as deforestation, overfishing, pollution, and climate change are already placing a significant strain on these resources. The carrying capacity of the Earth, or the maximum number of individuals that can be supported by the planet, is not a fixed number and is influenced by many factors such as technology, resource management, and environmental conditions.

However, there is a limit to the number of resources that the Earth can provide, and exceeding this limit can have catastrophic consequences such as famine, disease, and environmental degradation. The United Nations estimates that the world population will reach 9.7 billion by 2050, which will further strain the Earth's resources and ecosystems.

Therefore, it is not accurate to say that the Earth can support any number of humans in the future. Instead, it is essential to find sustainable ways to manage resources and address environmental challenges to ensure that the planet can continue to support human populations in the long term.

Disagree with the statement that "science and technology will ensure that food production and energy supplies keep up with the demands of a growing population."

While science and technology have made significant advancements in food production and energy supplies, there are limitations to what can be achieved. For instance, food production has been increased by modern agricultural practices, such as genetically modified crops and the use of pesticides, but these practices have also led to environmental degradation and the loss of biodiversity.

Furthermore, climate change is likely to affect food production and energy supplies, leading to decreased agricultural yields, disrupted water supplies, and more frequent extreme weather events, such as floods and droughts. This can affect food production and lead to a reduction in the availability of energy supplies.

Additionally, access to food and energy is not only dependent on technological advancements but also on social and economic factors, such as poverty, inequality, and distribution of resources. Even if technological advancements can increase food production and energy supplies, these advancements may not necessarily translate into equitable distribution and access for all individuals.

In conclusion, while science and technology have made significant contributions to food production and energy supplies, it is not accurate to assume that they will ensure that these demands keep up with the growing population. It is essential to consider the limitations of technology, environmental challenges, and social and economic factors to ensure sustainable and equitable access to food and energy for all individuals.

Disagree with the statement that "with seven billion people on the planet, water pollution is inevitable, and we should not waste money trying to prevent it."

Water pollution is a significant problem affecting the health and wellbeing of millions of people and the environment. Human activities such as industrialization, urbanization, and agricultural practices have resulted in an increase in pollutants in water bodies, leading to the deterioration of water quality.

However, it is incorrect to assume that water pollution is inevitable, and we should not waste money trying to prevent it. Several measures can be taken to prevent or reduce water pollution, such as wastewater treatment, improved agricultural practices, and industrial pollution control.

Wastewater treatment involves the removal of pollutants from wastewater before it is released into water bodies. This process significantly reduces the amount of pollutants in water bodies, making them safer for human consumption and aquatic life.

Improved agricultural practices, such as reducing the use of fertilizers and pesticides and implementing conservation tillage, can reduce the amount of nutrients and other pollutants entering water bodies.

Similarly, industrial pollution control involves the implementation of measures to reduce the number of pollutants released by industries, such as improved waste management practices and the use of clean technologies.

Therefore, it is essential to take measures to prevent or reduce water pollution instead of accepting it as inevitable. The costs of preventing water pollution are significantly lower than the costs associated with cleaning up polluted water bodies, treating diseases caused by polluted water, and the economic impacts on communities dependent on clean water resources.

Final answer:

The Earth's ability to support a growing population is not unlimited, and ensuring sustainability requires considering the availability of food, energy, and water resources. While science and technology have made advancements, uncertainties remain regarding their ability to meet the demands of a continuously growing population. Water pollution is not inevitable but is a significant concern due to the strain on water resources caused by the increase in population. therefore, option 1 is correct

Step-by-step explanation:

The statement that the Earth can support seven billion people now and will be able to support any number of humans in the future is not entirely accurate. While the Earth may have the resources to support a growing population, there are limitations to consider. The availability of food, energy, and water are crucial factors to sustain a growing population. While science and technology have made significant advancements in food production and energy supplies, it is uncertain whether they can keep up with the demands of a continuously growing population in the long run.

With seven billion people on the planet, water pollution is not inevitable, but it is a significant concern. The increase in population puts a strain on water resources, and if proper measures are not taken, it can lead to water pollution. Preventing water pollution is important because it affects human health, ecosystems, and biodiversity.
