It appears you’re interested in the forex market dynamics. The Euro’s weakening momentum typically means that it could be losing value against other currencies, particularly against the Yen if you’re focusing on the EUR/JPY pair. This could be due to a variety of factors such as shifts in economic indicators, Central Bank policy changes, as well as geopolitical news events that can affect market sentiment. To get a complete picture, it would be a good idea to look at the overall macroeconomic landscape, development of the Covid-19 situation in Europe and Japan, and monitor any key announcements from the European Central Bank (ECB) and Bank of Japan (BoJ). However, please remember that Forex trading involves significant risk and volatility.

1. **Coltan is a key resource**: Coltan, a combination of columbite and tantalite, is a mineral used primarily in the production of capacitors for electronic devices like mobile phones and laptops due to its ability to store and release electrical charge. Its properties make it valuable in creating components in aerospace, medical implant devices, and other advanced technologies. 2. **Mainly found in Central Africa**: Around 80% of the world’s known coltan supply is found in the African country of Democratic Republic of Congo (DRC). However, it can also be found in other countries such as Rwanda, Brazil, and Australia. 3. **Linked to conflict**: Coltan is often referred to as a conflict mineral due to the conditions it is mined under. In the DRC, the mining of coltan has frequently been linked to armed groups, including those involved in the nation’s civil war, who exploit the trade to fund their activities. 4. **Child Labor and Exploitation**: Coltan mining in the DRC is also associated with serious ethical concerns, including child labor and human rights abuses. Young children are often exploited and forced to work in dangerous conditions to extract the mineral. 5. **Environmental Impact**: The mining of coltan can have a profound impact on local ecosystems. Forests are often destroyed to make way for mines, affecting wildlife and local communities who depend on these ecosystems for their livelihood. Such mining activities also cause soil erosion and water pollution. Efforts are now being made to encourage responsible and sustainable mining practices in the industry. In response to these issues, several global initiatives have been launched to track the origins of coltan and ensure it is not contributing to conflict or human rights abuses. Examples include the Dodd-Frank Act in the USA and the standards established by the Organisation for Economic Co-operation and Development (OECD).
