Contemporarily, the greatest threat to sustainable engineering, has become unsustainable investments from 'High Risk' Economies such as Hong Kong, Taiwan in the South China Sea, and Ireland. When countries who are 'in-fledge' economies, where the economy is in significant financial and economic trouble, that it actually requires or is being provided Financial and Economic assistance from an external country, such economies should not really be investing in High-Tech industry. 


As the High-Tech industry is at the critical interface of human development and of human safety, a source of funding, that has an established risk of under-cutting technology, that may then become a danger for mankind, should really be resolved. 


Whilst bad technology from South China Sea, is a well known example, companies from Ireland have quite been under the radar. An Investment Bank from Ireland, who is investing in purchasing or leasing Aircrafts, is surely a risk for this world. When Ireland goes Bankrupt again, and requires monies from the other countries, it would be a fair expectation, that such downward pressure be applied on its Financial Institutes, who may then reduce funding for the safety of society. Imagine a few hundred aircrafts flying over your head, that has not been adequately serviced due to lack of funding by certain 'owners' of the aircrafts!


A Global Approval System for High-Tech Investors should really be developed that adheres to a Strict code for funding any High-Tech Investments.
