For the environment, which type of agriculture is least harmful, familiar or modern? Explain. ​

Answers

Explanation:

The environmental impact of agriculture is the effect that different farming practices have on the ecosystems around them, and how those effects can be traced back to those practices. The environmental impact of agriculture varies widely based on practices employed by farmers and by the scale of practice. Farming communities that try to reduce environmental impacts through modifying their practices will adopt sustainable agriculture practices. The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency.[1] Though some pastoralism is environmentally positive, modern animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia from cattle waste continues to raise concerns over environmental pollution.

Answer:

(Hope this helps can I pls have brainlist (crown)☺️)

Explanation:

The United Arab Emirates (UAE) is located in the Arabian Peninsula's southeast corner, bordering Oman and Saudi Arabia. The UAE was founded in December 1971 as a federation of six emirates: Abu Dhabi, Dubai, Sharjah, Ajman, Umm Al-Quwain, and Fujairah, with Ras Al Khaimah joining the federation in 1972.

The official religion is Islam, and the official language is Arabic. The UAE has the world's sixth and seventh biggest oil and natural gas reserves, respectively. The first president of the United Arab Emirates, Zayed bin Sultan Al Nahyan, managed the growth of the Emirates by spending oil money in healthcare, education, and infrastructure.

The UAE's economy is the most diverse of all Gulf Cooperation Council members, and Dubai, the country's most populated metropolis, is a worldwide city and international centre. The country has shifted its economic focus away from oil and gas and toward tourism and business. Although there is a corporation tax in effect and a 5% value-added tax was implemented in 2018, the UAE government does not charge income tax.

Religious minorities have strong social opportunities when
they

Answers

The best way to provide religious minorities with strong social opportunities is to let the minorities worship freely (option B).

Religious minorities include any group of people with a religion that is different from the dominant religions of a state, nation, etc. Some examples of religious minorities in the United States are:

Buddhists.Amish.Jewish.

Throughout history, these minorities have been vulnerable because their right to worship or express themselves has been limited. Due to this, minorities have not been able to strongly participate in society.

Based on this, the best alternative is to let minorities worship freely without vulnerating other religious groups. This will allow these groups to better express themselves and participate in society.
